Shidou swallows down every volley of spunk Denji shoots into his mouth. He keeps sucking until he's sure Denji doesn't have anything else to offer this round, then lets the other's cock pop out of his mouth.

"Fuck," he moaned out and then climbed up Denji's body to look him in the face, sticking out his tongue to show off some of the spunk still left on it, then pulled it back in and swallowed it down. "That was so fucking hot, Denji." He takes one of Denji's hands and puts it to his groin so he can feel how fucking hard Shidou is.

"Look, fuck, I'm so turned on." And he kissed Denji again.
